Diet Pills

I have been taking Tegretol for about a 1 1/2 years now for the one and only siezure episode I had back in November 2001. Since I started the medication I have gained a lot of weight and I want to go on a diet pill to help with my diet and excersize plan. The problem is when I look at the warning labels many of them have a warning for people with siezure disorders to consult a doctor. Is there any diet pill out there that one with a siezure disorder and on tegretol can take?
